What did the EACers do “right” to preserve conservative grading, and is it too late for other groups

Longacre

For some reason, I really like how the EAC group approaches the grading of early copper. There is a method to the madness, but it also takes into account many, many more factors that are overlooked by current TPGs. As a result, in my opinion, you get an “all in” grade, for lack of a better term, rather than some sort of seemingly inflated market grade that TPGs might provide, which takes an almost half-look at the coins being slabbed.

I long for the day when gold coins are graded under a very conservative, old-time standard, using a scale similar to the EAC rules. The EAC grading has also gone so mainstream that it is used frequently in auction catalogs, and not just within the closed confines of the EAC world.

Does anyone have any thoughts on what the EAC has done correctly in order to preserve this conservative way of grading? At what point did the EAC thumb its nose at the TPGs and decide to use its own system of grading? Is it too late for a similar system to be used for other series, such as southern gold? What would need to be done for these other series to gain widespread acceptance, or has the horse left the barn?
